Title:
WIRELESS CONTROL SYSTEM
Document Type and Number:
Japanese Patent JP3933897
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To elongate a sensing distance by raising a power for transmission and receiving and prevent multiple operation ends from being simultaneously operated.
SOLUTION: A portable telephone 4 having a short-distance radio wave transmitting/receiving mechanism is used. A gate controller 5 (5-1 and 5-2) added with a short-distance radio wave transmitting/receiving mechanism is used. The communication areas S1 and S2 of the gate controllers 5-1 and 5-2 are partially overlapped and the portable telephone 4 is positioned in the overlapped area S12. In this case, the portable telephone 4 transmits/receives data between the gate controllers 5-1 and 5-2 via the short-distance radio wave transmitting/receiving mechanism and displays gate names transmitted from the gate controllers 5-1 and 5-2 into a list. When a desired gate name is selected form the list of the gate name, an operation demand is transmitted to the gate controller 5 transmitting the gate name.
